275/35/18 tires in front with 285/30/18 in rear?! Good Idea or Bad?

[across5aprils]

If i went 275/35/18 in front for a 9 inch wheel and 285/30/18 in the rear would the diamtere difference be a big deal? cause it looked it up and the difference in diamter is that the 275/35 is about 25.57 inches in diameter and the 285/30 24.73 inches in diamtere. The sidewall height on the 275 is 3.78 inches and on the 285 its 3.36 inches. Will this look odd and will it be noticable? Cause im either going to go with that or go 275/35/18 all the way around. What would you do? And Im not going 295 so yeah ..out of these options what would be the best?

Sorry for all the tire questions but im ready to buy and need your help

It will look odd on any car except a GT500.

It's always a good idea to match profiles, 35 series for the front and rear.
If you dont the car will have a slight "nose-up" look that I personally dont like. I would advise against it. Some people will say you'll never notice it but we are car guys, we look and notice everything.

I calculated around 3/4 of an inch difference from your #'s..........not good!

I wouldn't, to me wrong and I'd notice. Try for a 285/35 rear, not a 30 series

It will look out of place with shorter tires. These cars have a large wheel well that needs to be filled up.

I switched the front's to a pair of 285's I got from Buyfordracing, the take off rims/tires from KR conversions.

During...

After...

The way it should have come.

^^ Sorry, but I don't think so...........4x4 trucks have same tires f & r.....go larger in the rear now and it's still a 'maybe'for me

40 series up front is a little big profile wise for me. I would use them on the back and find new fronts. It's your car though so you can do what you like!

I'm not sure of what you just tried to say...

The '03-'04 Cobra came with 275's all around and had better f/r weight distribution than the nose heavy GT500. The 285's on the 500 will help, however minor, to combat some serious understeer. I suspect the 285's didn't originally come standard due to their increased rolling resistance (read: reduced fuel economy) and increased cost. Beyond that they are a natural.

At the stock front ride height they don't...
